Multimeter is a hackable console for the game Screeps. It lets you access your Screeps console without loading up the full website (and as a result lets you play Screeps for much longer on a single battery charge), and is hackable with plugins.

Features:

• Terminal (command line) program, no browser or GUI required.
• Send console commands from the program.
• Rich console output formatting.
• Add plugins to get new functionality.

npm install -g screeps-multimeter
multimeter

When you run multimeter for the first time, it will ask you for your Screeps API token and save it into a config file in the current directory. You will also need to specify the name of the shard to use.

The main interface has a command line on the bottom. In type /help to see a list of the available commands. Type /quit to exit the program.

Console coloring and formatting is made possible by blessed's tags. Some of the tags you can use are:

• {color-fg} - Change the foreground color.
• {color-bg} - Change the background color.
• {bold}, {underline}, {blink}, {inverse}, {invisible} - Apply the character style.
• {/style} - Stop using the given style, e.g. {/bold}.
• {/} - Reset to normal characters.
• {|} - Align the rest of the line to the right.

Colors can be specified as a name, e.g. red, blue, yellow, cyan (see colorNames from blessed for a complete list), or as a hex code, e.g. #ffff00.

Multimeter currently ships with these plugins enabled by default. To select which plugins are loaded, edit the plugins array in your screeps-multimeter.json.

The alias plugin can be used to easily store and access commonly used console commands. Create a new alias by using /alias NAME COMMAND. Now, /NAME will automatically expand to COMMAND. For example, this alias will let you list all damaged creeps by typing /damagedCreeps:

/alias damagedCreeps _.filter(Game.creeps, (c) => c.hits < c.hitsMax)
/damagedCreeps

Aliases can also take parameters. There will be available in variables like $1, $2, etc. The entire passed string is available as $args. For example:

/alias hitsLeft "Creep " + $1 + " has " + Game.creeps[$1].hits + " hits left"
/hitsLeft Ryan

The watch plugin will log an expression to your console on every tick. To install it, copy watch-client.js to your script and add some code to your loop function:

var watcher = require('watch-client');
exports.loop = function() {
  // Rest of your code...

  watcher();
};

There are two ways to watch expressions. You can log it to the console normally by using /watch console EXPR. You can also log to a status bar at the bottom of the screen using /watch status EXPR. For example, /watch status _.keys(Game.creeps).length will keep a count of the number of live creeps at the bottom of the terminal.

Multimeter is built for hacking! The easiest way to add a feature to multimeter is to make a new plugin for it. If you need to change something and it can't be done with a plugin, you can fork multimeter and submit a pull request. Ideally, you can add the necessary hooks so that other plugins can take advantage of them.
